Abstract
The utility model discloses an omnibearing-observation type electricity test pencil. On the basis of the existing ordinary electricity test pencil, the electricity test pencil alters electrical connection structure. A neon tube is arranged on the top part position of the electricity test pencil. One end of two connection end points of the neon tube is connected with a hand-contact electrode. After the other end of the two connection end points of the neon tube is connected with a current-limiting resistance in series, the two connection end points are formed by a spring which is connected with a test contact head. The utility model changes the original observation bearing to top observation. Not only the utility model improves observation angles, but also the utility model enhances the application range of the pencil. The utility model has the advantages of firm and durable structure, convenient operation, etc.
Description
The utility model relates to a kind of voltage test device, the test pencil of the comprehensive observation of particularly a kind of energy.
At present, the domestic and international common test pencil that generally adopts, generally have following deficiency: (1) viewing angle is little, because be to adopt the side view mode, the contact is located at the top, when surveying some small-sized electrical appliances of inspection, can't observed place as lathe internal circuit, ceiling or other human eye, it is just very difficult to use common test pencil to observe, even causes misjudgment, and brings danger to the user easily.(2) electroprobe self intensity is low, and the neon tube placement location of common test pencil is general all in a body central authorities, causes pen as the hollow wall thin structure, thereby (especially in industrial and mining enterprises) in actual applications very easily cause damage, make cost increase.
The purpose of this utility model provides a kind of both sturdy and durable, can comprehensively observe again, and uses a kind of very easily test pencil.
Technical solution of the present utility model is: neon tube 4 is arranged on the top of electroprobe, and two links, one end of this neon tube connects hand touched electrode 5, and other end series connection current limiting element is after spring 7 connects test contact 5.
The top of insulation crust 2 of the present utility model is provided with a sphere of being made by transparent material and observes cover 1.In addition, said hand touched electrode 5 is arranged on a body side of electroprobe.
The utility model changes original observed bearing into top view, thereby has improved the observation sight line greatly owing to changed the syndeton of electroprobe, has improved the range of application of electroprobe.In addition, neon tube is moved to the top, can make a body make heavy wall or, can strengthen the intensity of pen like this, reach robust purpose near utility structure.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1: this test pencil comprises formations such as observing cover 1, shell 2, test contact 3, neon tube 4, hand touched electrode 5, current-limiting resistance 6, spring 7, resistor cartridge 8.This electroprobe is on the basis of existing common electroprobe, changes its electric connection structure and observed bearing thereof.Specific embodiments is: neon tube is arranged on the top of electroprobe, and two connection end points of neon tube, an end connects hand touched electrode 5, behind the other end series electrical current-limiting resistance 6, connects test contact 5 through spring 7 again.For improving viewing angle, the utility model is provided with a sphere of being made by transparent material and observes cover 1 on the top of insulation crust 2.Said hand touched electrode 5 is arranged on the outside of a body, and this electroprobe can be convenient for carrying and use as the pen of same Zhi Putong.
Claims (3)
1, a kind of comprehensive observation type test pencil, form by insulation crust (2) test contact (3), neon tube (4), hand touched electrode (5) and current limiting element (6) etc., it is characterized in that: neon tube (4) is arranged on the top of electroprobe, two lead end one ends of atmosphere pipe connect hand touched electrode (5), connect test contact (5) through spring (7) again behind the other end series connection current limiting element.
2, test pencil according to claim 1 is characterized in that: the top of insulation crust (2) is provided with a sphere of being made by transparent material and observes cover (1).
3, test pencil according to claim 1 is characterized in that: said hand touched electrode (5) is arranged on a body one side of electroprobe.
